Saturn's rings

“There are two main theories regarding the origin of Saturn's inner rings. One theory, originally proposed by Édouard Roche in the 19th century, is that the rings were once a moon of Saturn (named Veritas, a Roman goddess who hid in a well) whose orbit decayed until it came close enough to be ripped apart by tidal forces. A variation on this theory is that this moon disintegrated after being struck by a large comet or asteroid.The second theory is that the rings were never part of a moon, but are instead left over from the original nebular material from which Saturn formed” source:wikipedia
